Abstract

In certain systems where a series of stages are employed, it is desirable to control the action of a stage without possibility of interference form adjacent stages. A circuit of linked mutual exclusion elements is described which renders inactive the stages adjacent to an active stage, or inhibits action in a stage if any of its neighbors is active. This ensures that the stages adjacent to an active stage remain inactive, thereby avoiding problems associated with input events changing while an adjacent stage is active.
